Launch Base Error - YR CD

[Xenimme]

I've just signed up because i'm having some trouble with launch base, it isn't letting me run yuri's revenge (from the first decade disc), it brings up an error saying the CD is not in the drive, despite the fact it is. I've tried running YR on its own, and it works, i've run it using Ares and it worked, but running it from launch base brings me said error, i would attach the log file but it doesn't seem to be letting me do so. I really hope i can get some help with this as i really want to get this mod i downloaded running too (MigEater's D-Day).

Thanks in advance,

Xenimme
